Fourth Draft "Unsafe fp optimizations" project description.

[akbara]

if there going to be doing stuff like
if (a_float == someinteger)

imho this should be flagged off as a warning?
cause the data type obviously is better suited to be an integer.
and usually in floating point calculations you never do this (straight equality tests).
